Sourcing knitwear is not the same as buying cut-and-sew jersey. Flat-knit construction — the process behind sweaters, cardigans, and technical knitwear — requires machine programming, yarn procurement, and panel-by-panel production. The knitting itself is fast — a typical bulk order leaves our floor in 2–3 weeks — but the stages in front of it (sampling, revision rounds, yarn in-house) and behind it (three to five weeks of ocean transit) are what set the calendar. A brand that plans backwards from the factory quote alone will miss every season.

The numbers are straightforward: sampling takes 10–14 days in-factory, then shipping and approval rounds add another 1–2 weeks per revision cycle. Bulk production runs 2–3 weeks for a typical order — 3–4 weeks between 500 and 2,000 pieces, 4–6 weeks above 2,000. Ocean freight from Turkey (Mersin port) to the US East Coast is 3–5 weeks port to port, and US customs clearance and pickup add 5–7 days on top of that. From approved tech pack to goods in your warehouse: roughly 70–115 days — plan for 3 to 4 months, and up to 4½ for complex or high-volume programs.

A brand that wants Fall/Winter on the retail floor by September 15 must count backwards from that date: subtract 7–10 days DC processing, 2–5 days inland trucking, 5–7 days customs clearance, 3–5 weeks ocean transit, 2–3 weeks bulk production, 5–10 days yarn sourcing, 1 week pre-production sample, and 10–14 days for proto sampling plus 1–2 weeks for shipping and your approval round. That puts the tech pack delivery date in mid-May at the very latest — and once you allow for one revision round and the Eid holidays, the comfortable start is February or March.

Understanding the Lead Time Stack

Every stage in the supply chain adds time, and those stages are sequential — you cannot start bulk production before sampling is approved. Note where the time actually goes: the knitting floor is the fastest link in the chain at 2–3 weeks, against 60–90 days for the same program in China. From approved pre-production sample to a US port, the Turkish route runs 5–8 weeks against 13–18 weeks from China; customs clearance and inland delivery add the same 7–12 days on either route, so it is 6–9 weeks to your warehouse from Turkey against 14–20 weeks from China. The advantage is won at the machine, not on the water. Here is the full stack:

Stage	Duration	Notes
Tech pack to proto sample approval	2–4 weeks	Sampling itself is 10–14 days in-factory; the balance is shipping and your review. Each revision cycle = +1–2 weeks
Pre-production sample	1 week	If needed; can skip if proto is fully approved and unchanged
Bulk production	2–3 weeks	Typical order under 500 pieces; 3–4 weeks at 500–2,000 pieces, 4–6 weeks above 2,000. Yarn sourcing adds 5–10 days before knitting starts
Ocean freight (Turkey → US East Coast)	3–5 weeks	FCL from Mersin to New York/NJ, Savannah or Charleston — port to port; allow 3–5 additional days buffer for port congestion and vessel schedule shifts
US customs clearance	5–7 days	Depends on entry type, UFLPA review status, and CBP exam selection at port of entry
Inland delivery to DC/warehouse	2–5 days	Depends on your logistics setup and proximity to port of entry
Total: tech pack to warehouse	~70–115 days	Plan for 3 to 4 months; high-volume programs on a 4–6 week bulk run stretch to about 4½ months

Month-by-Month Buying Calendar

The calendar below maps key decision points for a US brand selling across multiple seasonal windows. The dates assume a typical run under 500 pieces per style — at 500–2,000 pieces add about a week to the bulk stage, above 2,000 add two to three weeks, and pull each PO deadline forward by the same amount. Use it to identify where you are now and what actions are overdue or on schedule.

JAN

Spring/Summer Proto Sampling Window

For brands selling Spring/Summer to wholesale retailers with a June delivery, proto samples should be in the factory in January and approved by the end of February. That leaves the bulk PO for late March and still lands goods in the first half of June. If your SS proto has not started by the end of January, you are spending your revision-round buffer rather than your schedule. This is also the window to open conversations about Fall/Winter — share concept direction and confirm factory capacity before it books up.

FEB

SS Proto Approval / FW Line Planning Begins

Spring/Summer protos should be signed off by the end of February, with the pre-production sample running in early March. That sets up a late-March bulk PO: 5–10 days of yarn sourcing, 2–3 weeks of production, a late-April sailing, 3–5 weeks on the water and 5–7 days of customs clearance put SS goods in your DC in the first half of June. Simultaneously, begin Fall/Winter line planning: yarn selection, construction direction, and initial tech pack development. FW yarn commitments made now lock in availability for premium fibers.

MAR

SS Bulk PO Deadline (End of March) / FW Tech Packs Out

Place the Spring/Summer bulk PO by the end of March for an early-June warehouse date. Yarn sourcing adds 5–10 days and production runs 2–3 weeks once yarn is in-house, so the container is ready to sail in late April. Finalize FW tech packs and send them to the factory this month — a March delivery rather than an April or May one buys you a full revision round without touching the FW bulk PO deadline. Review FW yarn samples and confirm colorways.

APR

SS Bulk Ships / FW Sampling Begins

Spring/Summer production wraps in the second half of April and the container sails from Mersin — from there it is 3–5 weeks of ocean transit plus 5–7 days of clearance before the goods move inland. Fall/Winter proto sampling is in production at the factory. Turkish holiday note: Eid al-Fitr (Ramazan Bayramı) date shifts each year with the Islamic calendar — confirm the exact date before setting your sampling deadline and add a one-week buffer around the holiday window. The days immediately before Eid are often disrupted as workers travel. Factor this into your proto delivery expectation.

MAY

FW Proto Approval Window / SS Bulk Crossing

FW proto samples arrive for your review. Evaluate construction, gauge, stitch quality, and fit against tech pack specs. Send consolidated, written revision feedback — one complete round of corrections is far more efficient than piecemeal emails. With bulk production down to 2–3 weeks, the sampling calendar, not the knitting floor, is where your season is won or lost. Spring/Summer bulk is crossing the Atlantic this month and clears US customs at the end of May for an early-June DC arrival.

JUN

FW PP Sample / FW Bulk PO Deadline (End of June)

With FW proto approved, the factory produces salesman samples or pre-production samples in confirmed bulk colorways. These represent what bulk will look like — evaluate color accuracy against your lab dip approvals, trim and label placement, and any construction details corrected from proto — then authorize bulk by the end of June. That is the deadline for a September 15 floor date: 5–10 days of yarn sourcing, 2–3 weeks of production, a late-July sailing, 3–5 weeks of ocean, 5–7 days of customs. At PO placement: transfer the 30% deposit, confirm the size/color breakdown in writing, and verify that your approved PP sample is the production standard on file. Spring/Summer goods land in your warehouse in the first half of June.

JUL

FW Bulk in Production / Vessel Sails Late July

Fall/Winter production runs 2–3 weeks and wraps in the second half of July, starting once yarn stock is confirmed. Final inspection is completed and the balance payment (70%) transferred before vessel departure — the container needs to leave Mersin by late July to make a September 15 floor date. This is where the deadline bites, and it is not the factory: a PO placed in late July or August still only takes 2–3 weeks to knit, but the 3–5 week ocean leg plus clearance pushes arrival into late September or October.

AUG

FW Bulk on the Water / Holiday Q4 Sampling Begins

The Fall/Winter container is crossing to the US East Coast through August — 3–5 weeks port to port from Mersin to New York/NJ, Savannah or Charleston. Turkish holiday note: Eid al-Adha (Kurban Bayramı) is the longer Eid holiday — 4 days plus travel time, with a production impact of approximately 7 days. Its date also shifts annually on the Islamic calendar — confirm the exact date with your factory and build a buffer if it falls in your FW production window. Simultaneously, Holiday and Q4 proto sampling begins now for brands targeting December floor dates.

SEP

FW Bulk Lands / Holiday Q4 Proto Approval

The Fall/Winter container reaches a US East Coast port in late August or early September, clears customs in 5–7 days and moves inland to your DC or 3PL in another 2–5 days — in time for a mid-September floor date if the vessel left Mersin by late July. Holiday/Q4 proto samples arrive for review and approval this month. Any revision round here eats directly into the Holiday bulk PO window — approve and move fast, because that PO is due in the first week of October.

OCT

Holiday Q4 Bulk PO Deadline (First Week) / SS 2027 Planning Starts

The Holiday and Q4 bulk purchase order must be placed in the first week of October: 5–10 days of yarn sourcing, 2–3 weeks of production, a late-October or early-November sailing, 3–5 weeks of ocean and 5–7 days of clearance put the goods in your DC between late November and mid-December. This is the last viable window for ocean freight — a November PO knits fast enough but lands in January, so it only works by air. Fall/Winter goods are already on the floor and selling. Begin Spring/Summer 2027 concept direction and open factory conversations — the planning cycle starts again.

NOV

Holiday Q4 on the Water / FW Reorder Window

Holiday production wraps at the end of October or in the first days of November and the container is crossing through November, clearing customs at the end of the month or in early December. If Fall/Winter is selling ahead of plan and you have fast-moving styles, the FW reorder window is now — production itself is only 2–3 weeks, so a reorder placed in early November can be air-freighted in time for late December, or shipped by sea for January restocking. Surface-level knitwear reorders are feasible; complex new styles are not at this stage.

DEC

Holiday Q4 Bulk Landed / SS 2027 Sampling Begins

Holiday and Q4 goods clear US customs at the end of November or in the first half of December and reach your warehouse or 3PL. Spring/Summer 2027 proto sampling should begin by late December for brands targeting a May–June delivery — that supports a late-March 2027 bulk PO. Share final SS 2027 tech packs with the factory before year-end — factories returning from New Year with confirmed programs move faster than those starting cold in January.

Turkish Holidays That Affect Production

Two Islamic holidays affect Turkish factory production significantly each year. Because they follow the lunar calendar, their Gregorian dates shift forward by approximately 10–11 days annually. Always confirm the current year's dates before setting PO or sampling deadlines.

Eid al-Fitr (Ramazan Bayramı)

A 3-day national holiday at the end of Ramadan. Factory closure is typically 3 days, but production impact is approximately 5 days — workers travel in the days beforehand, and the period immediately following the holiday sees reduced pace. Confirm the exact date each year before finalizing your sampling schedule. In recent years, Eid al-Fitr has fallen in late March or April, placing it directly in the FW sampling window.

Eid al-Adha (Kurban Bayramı)

A 4-day national holiday — the more impactful of the two Eid holidays for production. With travel time factored in, the production disruption is approximately 7 days. In recent years, Eid al-Adha has fallen in June, placing it in the middle of Fall/Winter bulk production. This is the single most disruptive holiday for FW delivery schedules. Confirm the exact date with your factory and add buffer before committing your FW bulk PO deadline.

Republic Day and National Holidays

Turkey observes several single-day national holidays: April 23 (National Sovereignty and Children's Day), May 1 (Labor Day), May 19 (Commemoration of Atatürk), August 30 (Victory Day), and October 28–29 (Republic Day). Each is a factory closure of one day. Individually, the impact is minor — but if multiple fall within a production window, the cumulative effect can add several days to completion time.

New Year and Winter Slowdown

Turkish factories typically observe January 1 as a national holiday. Unlike some Asian manufacturing regions, there is no extended winter shutdown in Turkey — production resumes normally in January. This is an advantage for US brands on tight FW timelines: you can realistically start a January tech pack delivery and expect the factory to be operational and responsive.

Common Planning Mistakes US Brands Make

These errors come up consistently with brands that are new to overseas knitwear sourcing — or that are applying jersey timelines to flat-knit programs.

Starting FW Tech Packs in April Instead of February

An April tech pack delivery puts proto sampling in May, approval in early June, the PP sample mid-June, and bulk authorization in early July. Production is only 2–3 weeks, so the container can still sail in late July — but that leaves zero slack. One revision round, one missed sailing or one Eid week and the 3–5 week ocean leg plus 5–7 days of clearance drops the goods in October, not mid-September. The fix: FW tech packs delivered to the factory in February or March, so the sailing date has a two-week cushion in front of it.

Not Building Revision Rounds into the Schedule

Every proto revision cycle adds 1–2 weeks: 10–14 days for the factory to re-sample, plus shipping time. A brand that assumes one flawless proto and plans their bulk PO accordingly will be 2–4 weeks behind schedule after a single revision round. Plan for at least one revision round in your sampling timeline, and build the corresponding buffer into your bulk PO deadline.

Placing Bulk PO Before Pre-Production Sample Approval

It is tempting to push bulk authorization ahead of PP sample approval to save time — but this is a false shortcut. Color, size spec, and construction surprises discovered at bulk are expensive and sometimes unfixable without remaking the order. The PP sample is your last practical quality gate before the factory commits yarn and machine time to your full production run. Approve it in writing first.

Forgetting Customs Clearance Time in the Backward Plan

Many sourcing plans calculate "factory shipment date = retail floor date minus ocean transit." The 3–5 week transit figure is port to port: US customs clearance and pickup add 5–7 days on top of it, and CBP exam selection can add 5–10 more. A CBP intensive exam during peak October port season can take 10 days or more. Always include customs clearance in your backward plan from the retail floor date.

Assuming the 2–3 Week Production Clock Starts on PO Date

Bulk production lead time begins when yarn is in-house and approved — not when the PO is signed. Yarn sourcing from Turkish mills typically adds 5–10 days before the knitting floor starts your order. For specialty yarns (cashmere, recycled blends, novelty fibers), that gap can be 2–3 weeks. When you place a bulk PO, ask the factory for a specific production start date and confirm yarn arrival timing.

If You're Starting Now — What's Still Achievable

Reading this in June 2026, here is a realistic assessment of what each seasonal window still looks like:

FW 2026

Difficult, but a Capsule is Possible

If a Fall/Winter proto has not been started yet, bulk cannot realistically be authorized before mid-July. Production is not the constraint — that is 2–3 weeks — but a late-July or early-August sailing plus 3–5 weeks of ocean and 5–7 days of clearance puts landed goods in mid-to-late September. A September 15 floor date for a full FW collection is gone. A small FW capsule (3–5 styles, limited colorways, existing construction types) can still hit an early-October floor date by sea with a fast approval process, or September by air if the margin carries it. Be honest with your factory about the compressed timeline and ask what is genuinely feasible in their current production queue — do not plan around a best-case scenario.

Holiday 2026

Achievable — With Room for One Revision Round

Holiday and Q4 knitwear is achievable from a June start. The bulk PO is not due until the first week of October, which leaves room for proto sampling in June and July, one full revision round in August, and a PP sample in September. Do not let that room evaporate: the December floor date is set by the late-October or early-November sailing and the 3–5 weeks that follow it, not by the knitting floor. Send a production-ready tech pack now and the schedule stays comfortable.

SS 2027

Ideal Window — Start Today

Spring/Summer 2027 knitwear is in the ideal planning window right now. Beginning the tech pack process in June for a late-March 2027 bulk PO gives you ample time for sampling, revision rounds, and pre-production approval — with an early-June 2027 US delivery. The stack itself only needs about three to four months; starting nine or ten months out is what buys you revision rounds, yarn options, and leverage instead of a scramble.
